What clues are in Apple's 22 October event invite? We puzzle over the latest cryptic invitation

Apple on Tuesday sent out official press invitations to its 22 October event, which we expect will see the unveiling of an iPad 5 and iPad mini 2, as well as new Macs and some new software, too. Here, we take a closer look at the 22 October event invitation and its design to speculate over possible clues hidden within it.

Apple is well-known for its cryptic event invitations, in which the company has previously hidden hints about what to expect during big keynotes. It looks like this invite is no exception, so here we take a closer look to see what we can uncover about the 22 October event.

Of course, we won't know for sure what Apple has up its sleeve until 22 October rolls around, but we can't resist trying to decode the invitation in order to satisfy our craving for more information.

The tagline Apple's tagline is a massive tease: "We still have a lot to cover."

It's been little more than a month since Apple's last special event that saw the iPhone 5c and iPhone 5s launch, so we expect that's where the word "still" comes in.

We can only assume that "a lot" is referring to Apple's iPad line-up, the iPad and the iPad mini, which are both due for a refresh this month.

We also expect that Apple is preparing an update for its MacBook Pro range, as well as the Mac mini, which are the last in Apple's Mac line-up without Intel's Haswell processors.

Additionally, there have been rumours that Apple is working on software updates, too, which could include iWork, iLife and Aperture, as well as a release date for OS X Mavericks.

New iPad Smart Cover coming? Finally, the word "cover" could be significant. With the new iPhones, Apple launched new case ranges. We've heard reports that Apple is working on a redesigned Smart Cover for its flagship iPad, as the iPad 5 is expected to be thinner and lighter than its predecessors.

We are slightly concerned about the possibility iPad cases, as we are less than keen on the cases for the iPhone 5c that were unveiled on 10 September.

The design Again, Apple has opted for a colourful invitation for its next event. In June, Apple's WWDC 2013 invite was colourful, and the event itself saw the preview of the new, colourful iOS 7. The invite for the 10 September event was also colourful, with bright circles scattered across it. It later became clear that this was a clue to the colourful new iPhone 5c.
